Title: Hot water heater
Inventor: FUNABASHI HIROYUKI
IPC: F24H1/10
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent condensation in a heat exchanger from being produced by flowing water to a bypass side upon operation interruption of an instrument by providing a bypass passage on a water passage where a heat exchanger is provided from a water supply hole to a hot water effluent hole for bypassing the heat exchanger, and further providing a solenoid valve between the bypass passage and the heat exchanger. SOLUTION: When an instrument is at an operation state, a solenoid valve 7 is at an open state, and when water is flowed to the instrument, a water amount detection part 6 detects a flow of the water to burn a burner 4. Hot water heated by a heat exchanger 2 and water flowing through a bypass passage 3 are mixed at a bypass outlet, and temperature of the mixture is detected by an effluent hot water thermistor 8, and a control part 5 controls the amount of combustion of the burner 4 such that the mixture temperature becomes set temperature. In contrast, when the instrument is at an operation interruption state, the solenoid valve 7 is closed to flow only to the bypass passage 3.  The solenoid valve 7 is closed upon instrument operation interruption as above, whereby condensation is prevented from being produced on the surface of the heat exchanger 2 because the heat exchanger 2 is cooled owing to flowing water.

Hereafter the calling jobs are continuously carried out in the selected calling mode until the power supply is cut off. When the power supply is once cut off, an initial state of a DTMF calling job is reset. The the calling mode is automatically selected again with the first calling action after the next application of the power supply. Thus it is not required for a setter to set again an internal switch of the facsimile device.
